11 May
Watched the granary hole; Ron is on the hillside
while Janet is over at the roost hole. This went on
through the morning (see compilation on back) during
which time 9524 laid again and 9523 came close to
entering but never did. We proceeded to put a
complete watch on the hole, but despite our efforts
we missed the egg-tossing, which did in fact occur as
the egg was gone when Ron checked the hole in the
evening. In any case, the nest is again empty.
12 May
Watched the hole again from 505-800 (see back);
9524 again laid but this time we saw it all: 9523
tossed the egg, following which Ron watched it
get eaten by the group members (I managed to find
the egg stuck up in the tree just after it was removed
[it was still intact]; I measured it and took some pictures
of it and then put it back. Ron then sat with the camera
and watched it get devoured.)
A success'. Meanwhile, Ron checked the other holes
to confirm that 9523 isn't laying somewhere else. The egg
laid by 9524 in the roost hole on the 10th is still there.
13 May
Watched from 520-910; both birds laid simultaneously
today so it's probably all over. 9523's (presumed) egg
was pretty small so it's possible that she might bag
them both; Ron stayed on for a while longer just in case.
